IBarcodeService Interface

Summary

Represents the WCF Service contract for a barcode service.

Syntax

C++

[ServiceContractAttribute(Name="IBarcodeService", Namespace="http://Leadtools.Services.Barcode.ServiceContracts/2009/01")] 
public interface IBarcodeService

<ServiceContractAttribute(Name="IBarcodeService", Namespace="http://Leadtools.Services.Barcode.ServiceContracts/2009/01")> 
Public Interface IBarcodeService

[ServiceContractAttribute(Name="IBarcodeService", Namespace="http://Leadtools.Services.Barcode.ServiceContracts/2009/01")] 
public interface class IBarcodeService

Remarks

Use the Read operation to search for barcodes within the specified area, or the Write operation to write linear, PDF417, MicroPDF417, Data Matrix, and QR barcode symbols over the image.
